POLYGHROME ATTACHMENT FOR LANTERNS.

Patented March 23, 1909.

Application filed April 6, 1907. Serial No. 366,699.

No. 915,865. Specification of Letters Patent.

To all, whom it may concern l Be it known that I, FRANK .KENXE), a citizen of the United States, residing at St.

Paul, in the county of Ramsey and State v 5 of Minnesota, have invented certain new i and usefulv Improvements in Polychroino At- 1 tachments for Lanterns; and I do hereby d clare the following to belayfull, clear, and exact description of the invention, such as 1.10 Will enable others skilled in the art to which it appertains to make and use the same. 1 My invention has for its object to provide 1 a simple and eflicient polychrome. attach ment especially adaptm for application to 3 lanterns, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the l claim. For ordinary use, a lantern having an un colored lobe andwhich will emit what is usually ilesignated as a Whiteliy'ht, is (lo-l sired; but it frequently becomes righly important to have available a lantern which 1 will emit a colored light, such-as a'red light for use in giving danger signals. My invention combines the above features in a single lantern.

The invention is illustrated in the. accomanlm drawin s wherein like characters l {J 7 i l 30. indicate like parts throughout the several views.

Figure l is a view in side elevation, show ing alantern having the improved polychrome attachment applied thereto. Fig. 2 is a detail in side elevation, showing means for causing simultaneous movement of the two colored wings or b'lades. Fig. 3 is a 1 transverse vertical se'c'tiontaken transversely through the lantern onthe line 11: .r" of Fig. 2, some parts being broken away. Fig. 4: is a transverse vertical section taken on the 1 line a a of Figl' The numera 1 indicates the framework, the numeral 2 the base shell, the numeral 3 E the oil cup, the numeral- 4. the wick, and the numeral 5 the globe of a lantern of the usual construction.

Referring to the construction illustrated in Figs. 1 to 4 inclusive, the numeral 6 indioperative position shown in Fig. 4 into their in the same view.

; on. said rock shafts and'made concave con-- cates a pair of reverscly constructed concave convex wings or blades which for ordinary purposes would be. OOhHlllllLfilQd of glass, but. might be nm-de of such material as isinglass or inica. 'lhese. blades are constructed veryaf much in the. shape of an oyster shell, and

, each is secured to a small rock shaft which is mourned in the sides of tho lmse shell 2. At one end, the shafts 7 project and are provided with intermeshing gears 8 which c0nnect the two blades or wings (3 for simultaneons movmnonts in reverse directions. One. of the shafts 7 is provided at one end with a small 0 )erating crank 7 by means of which the blades Ghiay bev moved from their inoperative position shown by dotted lines The free. edges of the blades 6 are cut away at 6" ,to afford an ample flame passage. Usually, the blades 6 would. be colored red so that when they are turned into operative position the lantern i will emit red light. By inspection. of Fig. 4

it evident that when the blades .6 are shown in Fig. 4 by dotted ines, they will be light from the {lame through the lobe 5, so that the said lantern may, when esired, be used in. the ordinary way.

\Nhat I. claim is:

The combination with a lantern having a has: shell, of a pair oflaterally spaced rock 3 shafts mounted in. and below the upper edge of said base shell, a pair of blades mounted vex both in vertical and horizontal direction and cut away at then free ends to all 0rd a llama passage. which blades are made of transparent material and are adapted to be moved to and from an inoperative pOSlt-IOII,

1 substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.-

FRANK ll. KENNEY.
